Using NLSY Kinship Links and Longitudinal/Cross- Generational Models: Cognition and Fertility Research

Specific Aims This application requests funds to extend our past NLSY kinship linking efforts, and to use recently developed kinship links in new and innovative empirical research. With previous support from a recent NIH grant, we updated kinship links for two National Longitudinal Survey of Youth datasets (NLSY79 and NLSYChildren/Young Adults), completed in 2013. The proposed research will identify and circulate links for a third NLSY dataset, the NLSY97, and will provide data for four proposed studies that use the kinship link structure from all three datasets. Our specific aims emerge from the structure built into the three NLSY datasets. The NLSY79 data, first collected in 1979 through a household probability sample of 14-21 year old U.S. adolescents (aged 49-57 in the 2014 release), represents a longitudinal database collected annually (early) and biennially (more recently) for 35 years. The NLSYC contains longitudinal data from all biological children born to the NLSY79 females (for whom childbearing is now complete), collected biennially since 1986, with an age range in 2014 from infancy to the early 40’s. The NLSY97 is an 18-year approximate replication of the NLSY79, with annual surveys from 1997 to 2012, then biennially from 2012 and continuing. Each data source has thousands of outcome variables related to work, family, health, cognition, and education. These NLSY data structures allow researchers to study: 1) Longitudinal patterns within a dataset; 2) Crossgenerational patterns across NLSY79 and NLSYC; 3) Cohort/period changes across NLSY79 and NLSY97; 4) Within-family patterns; 5) Cross-dataset outcomes using innovative research designs. Thousands of research teams from many disciplines have used the NLSY data. However, the data have one critical feature that limits their applicability to many research questions. They lack a linking structure of known genetic/social relationships across members of the sample. Our previous work has identified these relationships for the NLSY79 and NLSYC. The present work adds these relations to the NLSY97 and applies these links across the three data sets to answer novel questions.
